Please help urgently nobody ever seems to answer my questions! How do you work out the state of a substance at room temperature with only the relative atomic mass and the Mr (without the melting or boiling point) it says to use the graph. Will mark brainliest!!

You’ve pointed out on your graph where melting and boiling are.

It’s a solid if it’s before the melting point

It’s a liquid if it’s before the boiling point but after the melting point

It’s a gas if it’s after boiling point

Just use your graph and the points you’ve marked

Exothermic,  physical change after it is already baked

Answerd. may include all of these are many definitions of bases: the  brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.
